Did my iPod half-bricked ?

By saying bricked here, it doesn't mean it turn to a brick, not half-brick either. When I apply the greengr4ss patch the first time, it worked but got Cydia missing (backup.. dang, why I can't undo backup ?). I re jailbreak, redo, reapply greengr4ss, and stuck after "reboot". Even third time the charm, I still stuck. I think the bdev thingy had left some trace there, and can't untethered forever ? Or half-bricked ? I follow the quickfreedom, and stuck at creating firmware, so I used the firmware that I used it for the first time (which is success).

Alright sorry about my grammar, I am engrish. I say half bricked mean I never able to untethered (my theory, and I know it's wrong) with MY iPod (not become a brick and can't get in DFU, I can get in easily). Sorry, flame me down like other noob till I'm dust.

Edit: Finally got my dumb luck work. Use the txt in the greengr4ss folder. Luck on Friday the 13th.. Funny.
